Landhoow Door Latch Guard Stainless, 3″ x 7″
This stainless steel latch guard ships as a set of two guards, designed to reinforce doors with tight, offset latches. The 3 x 7 inch footprint, with about a 1/4 inch offset, covers standard latch areas and adapts to many door styles. Best for: homes or offices needing robust protection with minimal door modification. A limitation: verify lock distance before purchasing to ensure proper fit.
Why chosen: Durable stainless construction resists wear and rust, and the two-pack model helps secure more than one entry, which is ideal for small businesses with multiple exterior doors.
Door Strike Plate Reinforcement Plate
This double latch/strike plate replacement is designed for 5-1/2 to 6-inch hole centers. It combines latch and deadbolt strike plates into one piece, helping prevent jamb wear and plate separation. Best for: doors with misalignment issues or older frames needing a single, stronger guard. Limitation: it is a larger one-piece plate, which may require careful trimming to fit non-standard doors.
Why chosen: The longer opening accommodates seasonal wood movement and improves latch engagement, making it a practical upgrade for common entry doors facing misalignment challenges.

This heavy-duty hardened steel striker plate offers two holes for handles and deadbolts, compatible with 5-1/2 to 6-inch hole centers. It includes redesigned Torx reinforced screws to reduce wear and screw breakage. Best for: retrofit projects where enhanced screw integrity and smoother installation matter. Limitation: the stronger screws may require appropriate bit tools for installation.
Why chosen: It provides a one-piece replacement that helps secure the jamb against kicking or prying while accommodating seasonal movement through larger hole centers. The included bit and upgraded screws improve long-term reliability.
Prime-Line Satin Nickel Strike Plate
This satin nickel strike plate is sized for 5-1/2 and 6-inch spacing and designed to work with standard dead latch and deadbolt configurations. Best for: straightforward door upgrades that match existing hardware finishes. Limitation: may be less robust than heavy-duty reinforced plates for high-security settings.
Why chosen: It offers a simple, compatible retrofit option for existing doors requiring a finish match and reliable, basic protection against latch misalignment and jamming.
Buying Guide: Key Considerations When Choosing a Double Door Security Plate
- Door type and hinge orientation: Outswing vs. inswing doors affect guard placement and sizing. Measure latch center distance and ensure guard coverage aligns with latch area.
- Material and durability: Carbon steel and stainless steel provide corrosion resistance and long life. Consider environment (coastal, humid, or industrial settings).
- Size and fit: Standard sizes include 3″ x 11″ and 3″ x 7″. Check top/bottom clearances and offset for precise coverage on your door.
- Single vs. two-piece kits: Two-pack guards support multiple doors and easier replacement across a built environment.
- Installation requirements: Some products use Torx screws or reinforced fasteners. Ensure you have the right bit set and tools on hand.
- Security level vs. convenience: Heavier plates can offer better protection but may require modifications for proper fit and alignment.
- Replacement needs: If a door previously had misalignment issues, consider a one-piece reinforcement plate to fix alignment while upgrading security.
